Professor Leszczynski is an internationally recognized expert in biological and health effects of radiation emitted by the wireless communication devices. Among others, in 2009 he testified in the US Senate hearing on cell phones and health, and in 2011 he was one of the 30 experts, invited by the International Agency for Research on Cancer, which classified cell phone radiation as a possibly carcinogenic to humans.

We, the cell phone users, are seriously misled when buying a cell phone. We assume that this radiation-emitting product has been tested for human health safety before it was put on the market. We assume that cell phones are safe to use. However, this might be a wrong assumption.

In three separate epidemiological case-control studies, adult participants used regular, off-the-shelf, cell phones. These cell phones were built to fulfil ICNIRP safety standards. However, avid use of such “safe” phones, for a period of over 10 years, led to an increased risk of developing brain cancer.

This means that the current safety standards do not protect sufficiently users of cell phones. This situation of scientific uncertainty calls for an action – implementation of the Precautionary Principle.
